Key Descriptions

  • Usually 4-12 items for each section domain depending on which type of test is being
    performed (Short Form, CAT, or Profile)
  • Minimum and maximum scores depends on the form being used
  • Scoring: Item-levels are scored numerically for an individual's response to
    each question. PROMIS recommends the best way to find the total raw score is using
    the free HealthMeasures Scoring Service
    (https://www.assessmentcenter.net/ac_scoringservice) or a tool that can automatically
    calculate scores. Scores can also be added up by hand to find the total raw score.
    Then the raw score is converted to a T-score using the table in the Appendix of the link
    below. This standardizes the score with a mean of 50 and standard deviation of 10. Being above or below the standard deviation could be desirable or undesirable bases on the domain being measured.
  • Higher scores means more of the concept being measured. Example = more mobility

Considerations

  • PROMIS measures can be used in the general population and with adults and pediatric populations with a chronic condition(s)
  • PROMIS measures have a larger range of measurement than most conventional measures, decreasing floor and ceiling effects as a result
  • PROMIS measures have fewer items than conventional measures, thereby decreasing respondent burden. When used as computer adaptive tests, PROMIS measures usually require 4-6 items for precise measurement of health-related constructs
  • Translations: The assessments are available via PDF in Spanish and can be obtained in other languages by contacting translations@Healthmeasures.net
